摘要
报道了南京玄武湖Ⅰ,Ⅱ,Ⅲ,Ⅳ站从1987~1988一周年浮游动物种类组成和现存量的调查结果.浮游动物以原生动物为主.它占浮游动物种类数的61%,占总数量的97%以上,占总生物量的61%.根据污水分类系统的划分.通过对各站浮游动物种群和数量变化.以及指示种的分析,可有效地评价水污染情况.还与1978年抽查的结果进行了比较.10年来,浮游动物的种类.特别是原生动物的优势种发生了演替.浮游动物的种类在减少,而个体数量在增加.说明污染在继续.
In th pattern of seasonal fluctuation of zooplankton standing crop, the protozoan number was veryhigh-about 97% on average of the total zooplankton . According to the changes in number and biomassof zooplankton and indicator organisms. Water pollution was efficiently evaluated.- The conclusion 'indicated that Xuanwu Lake had undergone progressive eutrophication for ten years which was supported by direct comparisons between published acounts of the present day zooplankton species composition with reported for the Lake in 1978.
